#  Eva AI Assistant — remote installer
#
#  curl -fsSL https://appatalks.github.io/eva-agent/install.sh | bash
#
#  What it does:
#    1. Checks for git, python3, node (installs if missing and user confirms)
#    2. Clones the repo to ~/.eva (or updates if it exists)
#    3. Runs the local install.sh to set up all dependencies
#    4. Builds the standalone AppImage
#    5. Creates a symlink so `eva` works from anywhere
#
#  Options (passed as env vars before the pipe):
#    EVA_DIR=~/my-eva    — install location (default: ~/.eva)
#    EVA_YES=1           — skip all prompts
#    EVA_CHECK=1         — report only, don't install
#    EVA_NO_BUILD=1      — skip AppImage build
# ============================================================================
